Good point about Nvidia, but I think the problem with AMD is not so much shadyness as incompetence.
How are they ever going to compete with Nvidia when their marketing praises a new product while comparing their to past gen Nvidia or 2 year old Intel product?
Anyone researching their product and reading the marketing sees right through it and it comes off looking even worse.
The example Jedi gave of comparing your new truck model to a years old Tacoma model is perfect...
